Does not work syncing to Google Calendar. After you enter the Google user name and click Retrieve, the Google log-in page opens up in a tab of the current Firefox instance, which you cannot access while the Add-on window is active, so you can't get the Google tocken without closing the Add-on window, and then you can't paste in the token!!!
